Neural Network Based Protection of Software Defined Network Controller against Distributed Denial of Service Attacks

Software Defined Network (SDN) is a new architecture for network management and its main concept is centralizing network management in the network control level that has an overview of the network and determines the forwarding rules for switches and routers (the data level). Although this centralized control is the main advantage of SDN, it is also a single point of failure. If this main contro...

Mitigating DDoS Attacks Using OpenFlow-Based Software Defined Networking

Over the last years, Distributed Denial-of-Service (DDoS) attacks have become an increasing threat on the Internet, with recent attacks reaching traffic volumes of up to 500 Gbps. To make matters worse, web-based facilities that offer “DDoS-as-a-service” (i.e., Booters) allow for the layman to launch attacks in the order of tens of Gbps in exchange for only a few euros. A recent development in ...

Controller Placement in Software Defined Network using Iterated Local Search

Software defined network is a new computer network architecture who separates controller and data layer in network devices such as switches and routers. By the emerge of software defined networks, a class of location problems, called controller placement problem, has attracted much more research attention. The task in the problem is to simultaneously find optimal number and location of controll...
